In the year 1615, a new Shogun rises to power in Japan and strives to bring peace to the realm. In his battle against rebellion he recruits five specialists with extraordinary skills for assassination, sabotage and espionage.

Part of this team is Hayato, an agile Ninja who artfully defeats his enemies one by one from the cover of the shadows. Samurai Mugen fights with more strength. As the tank of the group, he can take on several enemies at once, at the expense of his agility. Aiko the Geisha is a master of camouflage and distraction, trapper Yuki is specialized in traps and deceptions. Takuma, being the eldest of the group, relies on his sniper skills for ranged attacks.

The player has to carefully evaluate his options in order to master the challenging missions: how will the characters behave as a team? Which one is best equipped for each task? How can they best master the given environments? Come up with your own ingenious tactics to vanquish enemies and complete missions.
